I am very new to Quantum GIS, I want to create a digital elevation map a particular region, I would very much appreciate if some one gives me a step by step procedure.
edit by Martin: I have the same question, but I want to create DEM from scan map (the territory of interest is aprox. 28 square km). Work flow: First open the map in an image editor (GIMP), select by colors with some tolerance and select the black color. Invert selection and delete non-black stuff. Save as Tiff WITH NO COMPRESSION. And then what is next step in QGIS with Grass Plugin? How can I get the contour values to the Tiff (my big problem)? After all is no problem make DEM from contours, I guess. Sorry for this "stupid" questions and thanks for all your replyings. Regards Martin
